摘要
本文利用储层地球化学方法,对川西致密砂岩气藏--新场气田中侏罗统上沙溪庙组(J2s)气藏储层进行了研究。将储层内部非均质性形成的化学机理和机械物理作用与储层所经历的构造演化史、成岩史、烃类运移富集史联系起来进行了综合分析阐述,同时结合油气产能、气藏动态特征、岩石学静态研究等资料,将气藏内非均质的储集空间划分为4类储集体,并指出了最有利勘探、开发的储集体类型。
Abstract
By means of reservior geochemistry,the tight sandstone reserviors of the Middle Jurassic Shaximiao formation (J2s) in Xinchang gas field,West Sichuan were studied.The chemical mechanism and physical action for formation of internal anisotropy of reserviors were synthetically analysed with the history of tectonic evolution,diagenesis and hydrocarbon migration and accumulation the reservior underwent.Meanwhile,4 types of reserviors were classified according to hydrocarbon producing potential,dynamic character of gas pool and petrologic data,and the most favourable zones for exploration and development were pointed out.
